    My model is Sony KP-57WM500, 57" Rear Projection. It shuts off by itself! I can turn it back on, but then it repeats the cycle! Is it the power supply?

    I have Sony KP-57HW40 model. It shuts off by itself too. It can be turned on with the red and white strip screen, but shut itself off again.

You can try the suggestion on the site I posted below. This site addresses a specific problem that tends to be fairly common in some Sony sets. Only try this if your sure that the problem your having is the same problem described in the site. Look at the picture of the screen on the site and see if that looks like your screen. The set on the site is red but it could be Green or Blue also. If you set won't stay on, you may have to turn the appropriate knob down slightly in order to get the set to stay on. Although he mentions this will fix a convergence problem, the fix described has nothing to do with convergence. The symptoms you are describing do not sound like a convergence issue. I am however a little concerned about the smell. Another thing is, after the set shuts off the Led will blink a code. For example it may flash 8 times then pause and repeat. You can Google this to find out more info on the problem. Many things can go wrong with TV's, I recommend you do as much research as you can to narrow it down. Good luck, here is the site.

New battery In mercedes no power


I'm not a car mechanic, but, it sounds like you might want to check the fuse to the ignition switch, and, if that fails, it might be a problem with the Start Safety Switch on the transmission. Good luck.

PS3 wont work


How long were you playing it? if you were playing for a couple of hours, then it could of just overheated, in which case the ps3 will shut itself off suddenly to keep from damaging something. It should work after about half an hour, adequate time for it to cool down, if not, then you might of damaged something.
